Limiting the DOT occupation to the specific DOT Industry shown

Many believe that the DOT Industry Classification(s) (DIC) shown with a specific DOT occupation code and description are the "only industries" in which this occupation is found.  This is not accurate, as the publisher of the DOT (both in the 1991 and in the 1977 edition) clearly states the following:

"In compiling information for the DOT, analysts were not able to study each occupation in all industries where it occurs.  The industry designation, therefore, shows in what industries the occupation was studied but does not mean that it may not be found in others.  Therefore, industry designations are to be regarded as indicative of industrial location, but not necessarily restrictive."
